Why 10 dimensions, why those shapes for the dimensions, why vibrating energy, and why any of it in the first place?


Really enjoyed this, but I have been reading a bit - and from what I understand superstring theory is losing favour as an answer to those questions.

What's replacing it is the "anthropic principle" which says that if those important numbers were different, then intelligent life would not exist to ask the questions about them.

physicists who follow the anthropic principle believe that there may be a multitude of parallel universes with lots of different rules and different numbers - we are here because we live in the one that has the right numbers for life.

I'm not a physicist- and I may be talking out of arse, but I find this a lot more interesting than SuperString theory - which looks like it's trying too hard to sell something shaky with pretty graphics. superstring theory calls for 10 dimensions - a small psychological rounding that makes it equal to the number of fingers we have. Not a coincidence in my mind.

I just realized that I had watched the string theory by Brian Greene video today as well and I was getting the 2 confused. The old brain-filling-in-the-blanks routine.

I fell asleep trying to watch this. It didn't start well did it with the crappy powerpoint presentation and leaving his mouse cursor visible. Then he edits in a large amount of that string theory programme with Brian Greene. Can anyone say how it ends? Does he find an acceptable definition of gravity? The suspense is killing me!

Michio Kaku - Parallel Worlds or Brian Green The Fabric of The Cosmos

Anything by Ed Witten, he is the guy that invented m-theory

In reply to your comment:
“I find this stuff extremely fascinating. Out of curiosity, can anybody suggest any good books to read on the subject matter? Thanks.”

I really think the preamble from www.tenthdimension.com is worth mentioning alongside this video. It's included right at the end of the video, but is only seen for a fairly short time:

"The "theory of reality" that I advance on this website and in the book "Imagining the Tenth Dimension" is not the one that is commonly accepted by today's physicists. Anyone wanting to know more about the currently established thinking behind string theory and the tenth or eleventh dimension should refer to such excellent books as "Parallel Worlds" by Michio Kaku, "The Fabric of the Cosmos" by Brian Greene, or "Warped Passages" by Lisa Randall.

I invite you to think of this as an entertaining diversion that for some people will have a strong and thought-provoking connection to their impression of how the world really works. If you click on "The Forum", you will be taken to a page that gives readers an opportunity to debate the concepts presented in the book and this website more fully. Enjoy! " - Rob Bryanton

The presentation in the video suggests that it is presenting factual information, so I think it's important that it be qualified as what it really is: a hypothesis.

With all that said, an excellent video.

This is a fantastic series by an excellent author/narrator/host Brian Greene. The whole thing is like 15 parts, as I recall with potentially great error.
